Muscles of the Shoulder Girdle EXPLAINED | Origin, Insertion, Action, & More

The video tutorial explores shoulder girdle muscles, focusing on their anatomy, origins, insertions, actions, and innervations. It covers the trapezius muscle's three parts, the pectoralis minor, serratus anterior, levator scapulae, and rhomboids. The tutorial explains how these muscles contribute to scapular movements, such as elevation, depression, protraction, retraction, and rotation, and highlights the importance of the serratus anterior in preventing scapular winging.

What is scapular winging and what causes it?

What are the origins of the levator scapulae muscle?
